Hi there,

I'm getting the following error whilst building danecheck on Amazon Linux 2:

Building all executables for `danecheck' once. After a successful build of all of them, only specified executables will be rebuilt.

    Process exited with code: ExitFailure 1

Any idea how I could solve this? I tried googling the error but it's not yielding results and I'm not proficient with Haskell.

Kind regards Meint

I received the same error; took a little research to track down how to fix it (as I've never used Haskell either :). Looks like the snapshot doesn't include a compatible TLS dependency, but you can manually add a later version of tls with the following addition to stack.yml, just after the "extra-deps:" line:

- tls-1.5.2@sha256:61e403d59c860fe9df2ff15bf2aa73a75fa1fb53f7ac27a62d1f40f23d30f26c,6753
